' b all whomit may concern.- i

Be it known that I, VERNON Hoxrn, a citizen of the United States, and aresident of Adrian, in the county of Lenawee and State of Michigan, haveinvented a certain new and useful Staple Forming and DischargingMechanism; and I do hereby declare the following to be a full, clear,and exact description of the invention, su'ch'as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the figures ofreference marked thereon, which form a part of" this specification.

My invention relates to wire-working machinery, and particularly tomechanism for use in wire fence making machines or the like-forsuccessively severing sections from a wire intermittently fed thereto,forming staples therefrom, discharging such staples from such mechanismand clamping them about registering intersecting portions of a fabricbeing woven. The invention is not restricted to use insuch connection asit may be used in any connection forwhieh it may be adapted or appropriate.

The object of my inventionis the provision of an improved and highlyefficient mechanism of this class, which is simple in its operation andconstruction, composed of a minimum number of parts, and is particularlyadapted for'use in narrow spaces whereby a number of the same can beplaced side by side and used in machines for manufacturing fine meshedfabric, such, for instance, as chicken fabric or the'like.

The operation, construction and arrangement of the parts of theinvention are fully described in the following specification, and whilein its broader aspect it is susceptible of numerous modifications, apreferred embodiment of the same is illustrated in the accompanyingdrawings, in which,-

Figure 1 is'a side elevation of the'invention, with a portion brokenaway and the movable parts at their limit of forward movements. 2 is anopposite side elevation thereof, with a portion broken away andthedischarging plunger at the limit of its rearward movement relative tothe male staple forming part. Fig. 3 is an enlarged front elevation ofthe upper portion of the same looking in the direction of, the arrow inFig. 2. I ig.v 4 is a side elevation of the mlevice similar to that ofFig. 2, with the mpvable parts in full retracted position. Fig. 5 is anenlarged top plan view of the forward portion of Fig. 4:. Fig. 6 is anenlarged inner sideview of the upper staple forming and guiding part,with associated similar to Fig.6 showing successive stages of the stapleforming operation in dotted lines, and Fig. 8 is a similar view withdifferent parts in section and theplunger in the'aet of ejecting'astaple from the device.

Referring to the drawings, 1' designates what maybe termed the holder ofmy in vention, which is suitably secured in proper position 1n themachine in' which it is to be used, as is well understood in the art.'The inclined, as indicated, and vertically grooved or recessed from itsrear end forwardly, as at 2, Figs. 1,6 and 7,'to receive the plunger 3.The recess andplunger 3 are shown as being provided in their sides neartheir upper edges with complemental grooves t and is provided atitsforward end with a stapledischarge nose 6,'wh1ch 1s adapted to worktension 7 in the forward end of the holder. Mounted on one side of theholder 1 is a recipro-catory plate or member 8, which is held to theholder and guided for reciprocatory movements relative thereto due tothe lower portion of such plate being broadened and flanged to slidinglyinterlock with a complement-a1 portion of the holder, as shown at 9.upper portion projecting above the top of the holder and provided at itsforward end with a tongue which project's laterally therefrom in adownwardly extemling curve, with its free end .tern'linafing immediatelyover the plane of movement of the discharge nose (3 when at its limit offorward movement. The planes ofmovementof the plun gel-.3 and plate 8slightly diverge from the forward end of the holder rearwardly to causethe end of the tongue to gradually lower into the path of movement ofthe purpose of forcing a staple back in the discharge-way after enteringthe same.

The tongue 10 which forms both the male staple formingmember and thestaple-slide of my invention, when moved rearwardly Patented Feb. '7,i911;

portions of the holder. Fig. 7- is a view' ribs 5 to guide thereciprocatory movements of the plunger m the holder, and the plungerinto a staple-discharge way or shallow ex-' upper surface of this holderis preferably The plate or member 8 has its plunger-nose on its rearwardstroke for the rig from 'its'for'wa rd position, cooperates 'with alower block or subjacent portion .11 of the holder and-with theoverhanging part 12 of a block or portion 13 of the holder to form intoa staple aseetion of wire previously fed thereto and severed ashereinafter described. The block'or portion 11 is disposed on the top ofthe holder 1 at the side of the staple discharge-way 7 which iscontiguous to the plate 8 and is immediately at the rear of an incut 14in the contiguous side of the holder, through which incut the staplewire a feeds. The forward endor nose of the block or portion 11' istapered fronrits outer side edge inwardly to the edge of thedischargeway 7, as indicated at '11 Fig. 8, to guide the coactingstapleleg thereto on the rearward or staple forming movement of theplate 8.

The portion 13 is shown in the present instance as comprising a block,which is secured to the top of the holder at the side of thedischarge-way .7 opposed to the plate-S and has" the part .12 projectinglaterally from its inner side'over the discharge-way and in contiguousposition with the plate 8.

The under side of the part 12 is curved in substantial parallelism withthe tongue 10,

as is also the top of the blockfjll, and suitably spaced from such blockto permit the tongue 10 to freely pass therebetween. The

forward portion of the part 12 is undercut or fashioned on theunderside, thereof to form a shoulder 15,which faces to the front andhas the end thereof adjacent to the plate 8 starting near the frontend-of said part, thence continueslaterally and rearwardly in spiralform to immediately above the plane of movement of the plunger, andterminates in the straight surface 16, which continues rearwardly for adistance in contiguous parallel relation to the plane of -movement ofthe plunger-nose 6, as best shown in Fig. 6. It is thus apparent that ona rearward movement of the tongue 10 ,the undercut surface 17 of thepart 12 cooperates therewith and with the surface 1 of theholderimmediate'ly in advance 'ofthe block 11 to form into U-shape asection of .wire drawn therebetween, while the spiral shoulder 15 causesthe upper leg of the staple to swing laterally to the horizontal planeof the lower leg during the forming operation and at the same timecooperates with the tapered nose of the block 11 to guide the stapleinto the discharge-way in advance of the plunger-nose 6.

18 designates an oscillatory wire-cutting knife, which is mounted in an:ineut in the side of the holder 1 at the forward end I thereof and inthe path of movement of the lower forwartl portion of the plate 8, seeFigs. 2 andi l. This knife is pivoted to the holder as at 19, and has anupper nose portion 20 provided with a vertical aperture the upper edgeof 21 thercthrough for guiding the feed of the wire-thread a to thestaple-forming parts. Thetop edge of the knife 'is rounded to adapt itto continue in shearing contact 'with the fixed shoulder or cooperatingshearing edge 22 of the holder. The oscillatory movements of the knifeare limited in either direction by shoulders on the holder, and areactuated by a cam member 23 on the forward end portion of the plate 8working in a recess and against a cooperating cam surface onthetail-piece 25 of the knife. When the knife is at the limit of itsforward, movement the upper end of the aperture 20 therein registerswith the' incut 1 1 in the holder side, and when in this positionalength of the wire a is fedto the forming parts, as indicated in Fig. 2,by

any suitable intermittent feeding-mecha- 1 nism, such, for instance, asthat shown in my former United States Letters Patent No. 879,965 of Feb.25, 1908.

Rising from the plunger 3 is a block or part 26, which has a lug 27projeeting'from one sidethereof and working in a'longitudi-'nally-extending slot 28in the plate, which slot is shorter than thestroke of the plunger tocause the plate to move with the plunger duringportions of its movements and to permit it to remain stationary relativeto the plunger during the balance of its move-- ment. I 1

29 designates-an arm, which lies parallel to the plateS at the innerside thereof and has its forward end pivoted, as at 30, to

the forward end of such plate and has its rear end reduced on both itsupper and lower edges to-form the beveled shoulders 31 and 32 at theinner. ends of such reduced edges, the upper shoulder 31 being inadvance of the lower one, as shown in Figs. 1, 2 aud t. When the plungeris at the limit of its.rear stroke the reduced end of the arm 29 restson the top of the block or part 26 thereof with its shoulder 32 inabutment with the beveled edge 26 of such part and is held in suchposition by a finger 33, which rises from one sideof the holder 1 nearits rear end and has its upper end angled to adapt it to overhan andcoact with the arm 20, showm in Fig. 4. 'On the forward stroke of theplunger the block 26, coacting with the shoulder 32, forces the arm .29and attached plate 8 back to their forward posi- As the plate 8. reachesits limit of tions. forward movement, the upper reduced edge of the arm29 moves under the overhanging portion of the finger 33 to permit therear end of the arm- 29-to raise to release the engaged beveledshoulders 32, 26, which raising is accomplished by the action of saidbeveled shoulders, 'as is apparent, thus permitting the plunger tocontinue its forward movement alone to discharge a staple from lBU,

the holder, as is apparent. On the rearward stroke of the plunger thelug 27 is timed to engage with the plate 8 at the rear end of the slot28 as the block 26 moves under the lower reduced portion of the arm 29,and, on the continued rearward movement of the plunger, the beveledshoulder 31 on the arm 29 coacts with a corresponding beveled surface33' on the finger 33 to effect a positive lowering of the linger 29 inposition for its shoulder 32 to enact with the beveled edge of the block26.

3 1 designates a plunger actuating table, which is slidingly mounted tothe rear of the holder or holders and connected to the plunger-s thereofby links This table maybe actuated in any suitable manner, or

any other means may be employed to actuate the movements of the plungcrsof the associated holders.

The operation oi my invention is as follows:During the relativemovements of the plunger 3 and plate 8, or while said plate. is in itsforward or stationary position, a predetermined length of the wire a isfed through the aperture in the knife 18 and up through the incut 14 inthe holder-to the' rear of the forming tonguelO Fulfill) advance of thefemale forming parts 12 andi On the initial rearward movement of theplate 8, which is accomplished by the lug 27 moving into contact- Withthe plate at the rear end of the slot 28 and moving the plate therewith,the knife 18 is oscillated,

due to the coaction of the cam 23 with' the .cam surface of thetail-piece 25 ot' the knife as it recedes from the recess 24 therein,and

a consequentsevering ot the fed section of wire accomplished by theshearing action of the knife and edge 22; of the holderf Atapproximately the period of severance of the section. of Wire, suchsection is gripped between the coacting forming surfaces, and on acontinued rearward movement of the tongue 10 with the plate 8 is drawnbetween the surfaces 16 and i7 and formed into i?- shape thereby. Duringthe forming opera tion of tl staple the lower leg thereof is moved intoregister with the staple dis chargeway 7 due toils coaction with thetapered enc upper log a caused to desc'ibc a quarter turn with the lowerleg as its" axis and is guided into the discl 1r ia ge-way in advance ofthe plunger nose by the action thereon oil', the spiral .houlder 15 andstraight portion 16 or the block 14:- During the continued rearwardmovement the staple held in the discharge- "'ay by said portion 16. itis' thus seen that the tongue 10 both serves as the male forming memberand to guide the movements o the staples to discharging positirm. in theforward stroke of the piunger, the staple is lischarged from the who 7nntl clenched about or to an alining ll." of the block 11., while theobject. The plate 8 also returned to its forward position on the forwardstroke of the plunger by reason of the coaction of the edge of the block26 withthe beveled shoulder 32 on the arm 29, which coaction is releasedas thenpper reduced edge of said arm passes under the angled end of thefinger 33, thus permitting the plunger to continue its forward movementalone, due to the-h1g2? working in the slot.- 28.. The forward end ofthep'late 8 is notched on its inner edge, as at 36,36, to receive thelegs of a staple as it assumes an angle relative to -the discharge-waywhenbeing formed and turning to horizontal position.
